CPU Comparison
Core i5-1235U (IPU) vs Intel Core i5-12450H
A side-by-side comparison of specs, performance and value. The Intel Core i5-1235U is a mobile processor that represents a fascinating blend of performance and efficiency, tailored for thin-and-light laptops and specialized business environments. Launched in early 2022, it utilizes Intel's Alder Lake-U architecture, bringing a hybrid design to the mobile space. What sets this specific SKU apart is the inclusion of an Infrastructure Processing Unit (IPU), designed to offload infrastructure tasks like networking and security from the main CPU. With 10 total cores—comprising 2 Performance cores and 8 Efficient cores—and 12 processing threads, it handles multitasking with surprising agility. The chip operates at a base frequency of 1300 MHz on its P-cores and can boost up to 4.4 GHz under load. Its 15W default TDP makes it ideal for portable devices, ensuring long battery life while maintaining the processing grunt needed for modern office workloads and background data management.
